Abstract: Vehicle commodity evaluation can play an important role in the early stage of vehicle research and development. Based on a series of virtual reality technologies and combined with a multi-dimensional adjustable semi-physical stand, a virtual verification platform was built to realize the one-to-one mapping between real space and virtual space, and between real human body and virtual human body. In the data phase of product development, the digital model is visualized as a Digital Mock-Up, the commercial evaluator performs subjective evaluation and verification analysis on the typical static scene of the Digital Mock-Up from the user's perspective by wearing motion capture device. In front of the physical sample vehicle, product design problems such as the perceived quality of interior and exterior decoration, human-machine space and usability, and maintenance convenience are discovered. Through the pilot verification of several products under development, the results show that the virtual evaluation of vehicle commodity can make the early verification of product research and development more efficient, more sufficient and lower cost. Based on this, the paper puts forward the application deepening direction of virtual verification in the evaluation of vehicle commodity, which has a strong reference significance for product verification practitioners.
